    noise to signal ratio

    I could not find any information on the E-2000 but I did find lots of info on the E-200D. Everything you need to know about setting the output level is in the operators manual. I think you are overlooking some details associated with the terminology. 0dbm is 1 milliwatt. (0.001 watts) and...

    noise to signal ratio

    http://www.minicircuits.com/pages/pdfs/dg03-110.pdf -67 dbm at antenna connector = S9 (solid state) At -50 dbm your Smeter should indicate +17 db over S9.

    THANK YOU! An impedance mismatched transmission line does not cause CMC's.

    Low Volume

    I did not have a clue about that. I wonder if that is regional or nationwide. Funny you should mention the Real McCoy; That is my surname. Thanks for the info.

    PENETRATER HB-200

    Not at CB Tricks under Penetrater. I will try the other name you threw out. This has no filtering and is running unreg. 22v no load. Transformer looks substantial enough to cover the 2879's but I have never driven it with more than about 18 watts pep. Thanks for the info. It might lead me...

    460 to 465 mobile antenna

    I would go with Captain K (post #2). You can homebrew one easy enough and try it out. If you find it insufficient then you can throw money at it.

    MS119 SUPER SCANNER weird swr?

    I visited this web site associated with the link shown in the previous post and read the article and download the software and NO WHERE DOES IT SAY ANYTHING ABOUT A "1/4 WAVE MATCHING STUB" being associated with the Super/Scanner type of antenna. It talks about the feed lines going to their...

    HY-GAIN SPT 500 PENETRATOR TUNING

    A friend got a Sirio Tornado 27 and he is more than happy with it. He has it 40 feet to the feed point and he is the strongest local signal for the same distance and same power. And it appears that he is hearing better than most.

    HY-GAIN SPT 500 PENETRATOR TUNING

    He doesn't have one yet. He is in pursuit of one. He's in Ireland and has to find out what is involved in getting one shipped to him. He just wanted to get some information about it afore hand so that he can factor that into the whole picture and help him with his decision about getting one...

    Ok, thanks. I'll hit Marconi up about it.

    Transistors ? 2SC1969 Verses NTE 236

    You can probably get an good idea about how long it is going to last by how hot it is. You can monitor the heat with your finger. If after talking for a while you find that it is extremely hot then it probably ain't gonna last too long, but on the other hand if it runs just on the warm side it...

    HY-GAIN SPT 500 PENETRATOR TUNING

    I will look into this further. Maybe the tunning is done with altering the dimensions. Longer or shorter?

    ¿ is height really might?

    Two days might be a little too soon to rush to judgement. Consider leaving it where it is and get another and put it where the other one was, and then you have a better way to compare.

    I think I am interested, just depends on how you are allowed to use it. If you are already familiar with this maybe you could give me a primer so I can know what to expect. Thanks, RadiooMan

    MS119 SUPER SCANNER weird swr?

    Evidentally you have been misinformed; A coaxial stub does not have to be an electrical quarter wave length. And if you bothered to think this through you would realize the error of your thinking A shorted 1/4 wave stub would theoretically present an infinite impedance at the other end and how...

    MS119 SUPER SCANNER weird swr?

    It might be mechanically 1/4 wave but electrically it's not. It is not a 1/4 wave, but it is a stub. The owners manual says it is approximately 9 foot of RG-58 shorted on one end. Now unless you are willing to dispute what the owners manual says then this should be the end of this...

    MS119 SUPER SCANNER weird swr?

    I cannot say with absolute certainty, I would asssume that the unshorted end of the ~9 ft long coax (RG-58) would attach as follows: Shield to shield of the other coax shields and then the center conductor of the matching stuf would attach to the appropiate relay contact.
